For the 2016 Chevrolet Impala, both the low-beam and high-beam headlight bulbs depend on the factory headlight system. Models with halogen headlights use 9005 bulbs for both functions. Models with HID headlights use D3S bulbs for both low and high beams.
The daytime running light setup also varies: halogen-equipped models use 9005, while HID-equipped models use an integrated LED daytime running light.
